DESCRIPTION  
The TPA2005D1 is a 1.4-W high efficiency filter-free  
class-D audio power amplifier in a MicroStar Junior™  
BGA, QFN, or MSOP package that requires only  
three external components.  
–
Optimized PWM Output Stage Eliminates

–
Internally Generated 250-kHz Switching  
Frequency Eliminates Capacitor and  
Resistor  
Features like 84% efficiency, -71-dB PSRR at 217  
Hz, improved RF-rectification immunity, and 15 mm2  
total PCB area make the TPA2005D1 ideal for  
cellular handsets. A fast start-up time of 9 ms with  
minimal pop makes the TPA2005D1 ideal for PDA  
applications.  
–
–
–
Improved PSRR (-71 dB at 217 Hz) and  
Wide Supply Voltage (2.5 V to 5.5 V)  
Eliminates Need for a Voltage Regulator  
Fully Differential Design Reduces RF  
Rectification and Eliminates Bypass  
Capacitor  
In cellular handsets, the earpiece, speaker phone,  
and melody ringer can each be driven by the  
TPA2005D1. The device allows independent gain  
control by summing the signals from each function  
Improved CMRR Eliminates Two Input  
Coupling Capacitors  
while minimizing noise to only 48 µVRMS
